The pore structure parameters derived from resistivity parameters are variable with water saturation, and the magnitude and rate of their variations can reflect the change of fluid distribution in reservoirs in the recovery process.

• 结果表明:从电阻率参数计算得到的岩石孔隙结构参数能较好地反映岩石的孔隙结构特征,利用电阻率计算得到的岩石孔隙结构参数是随含水饱和度变化而变化的量,其变化量及变化的速率能够反映出储集层开采过程中油气藏内部流体的分布变化;
